How often have you unexpectedly had a couple of hours free in your schedule, only you can’t think of anyone who could meet you at the nearest tennis court for a quick match right away? Well, now there’s a unique mobile app that can solve that problem within a matter of minutes.

With Tennis Buddy, users can connect with fellow tennis players in the nearby area who are looking for hitting partners or match opponents at any given moment. The location-based app has more than 8,000 users and is now established in 10 cities, each with more than 200 people who are in search of a game of tennis.

“When building Tennis Buddy, I wanted to especially help the people who often only have a two-hour window of spare time that opened up due to a cancelled meeting, for instance,” said Tennis Buddy co-founder Marius Kraemer. “Our broadcast feature allows our users to ping all tennis players nearby to let them know that they want to play. With a userbase of over 350 in London and 900 in L.A. already, there is always at least one person who is available at that very moment, which brings down the average response time to a broadcast to under 10 minutes.”

Features of the Tennis Buddy app include the ability to filter by different criteria such as distance, age, gender and skill level. Users can also check out all local player profiles and view feedback ratings they have received from other Tennis Buddy players. To find a buddy, users simply post a broadcast that will be instantly received by all tennis players in the area. Specific players can also be targeted to receive the broadcast.

In addition to finding a hitting partner, Tennis Buddy can also help business professionals or travelers who visit a new city. Tennis Buddy’s ability to connect users to locals who know the area can help users get to know foreign cities from a resident’s perspective, and could easily spark new friendships. The reason for its success, according to both Kraemer and co-founder Sophia Vogt, a former Division-I tennis player, is that sports are a great way for people to meet and get to know each other.

By year’s end, Tennis Buddy aims to have 500 users in over 100 cities each, connecting people across all the international cities of the world.
